1. 解压二进制包到个人目录，例如/home/liyh/local/mysql；
2. 拷贝一份系统目录的my.cnf配置（或者后面的配置样例也可以），按照如下方式修改：
2.1 将其中所有目录相关的配置全部改为个人目录，且要用绝对路径，不能用$HOME. 例如data, log（注意二进制包解压后缺省并没有log、tmp目录，需要自己手工创建），为了提高性能，建议数据目录和日志目录分开到不同的盘不同的目录，例如：
datadir = /home1/liyh/mysql/data/
log-error = /home/liyh/local/mysql/log/mysqld.err
log-bin=/home/liyh/local/mysql/log/mysql-bin
innodb_data_home_dir = /home1/liyh/mysql/data
2.2 修改[mysqld]下的port为你自己的端口；
2.3 修改[mysqld]下的user为你的用户名；
3. 将mysql的目录权限修改为你的用户，例如：
chgrp -R liyh mysql;
chown -R liyh mysql;
chmod 775 mysql;
4. 到mysql目录下的scripts目录，执行如下语句：
./mysql_install_db --defaults-file=/home/liyh/local/mysql/my.cnf --user=liyh --basedir=/home/liyh/local/mysql
5. 执行如下语句启动：
/home/liyh/local/mysql/bin/mysqld_safe --defaults-file=/home/liyh/local/mysql/my.cnf --basedir=/home/liyh/local/mysql &
【特别注意】为了提高InnoDB引擎的性能，记得一定要按照如下方式修改两个参数，否则你的MySQL insert和update慢得如蜗牛，但高性能同时也是有损失的，这样配置会降低MySQL的可靠性，某些场景下可能丢失数据，实际应用需要你自己评估是否要这样配置：
sync_binlog=0 1代表每次执行一条insert/update/delete都同步一下磁盘，0代表由操作系统决定何时同步磁盘，大于0代表达到多少条后再同步磁盘，如果可靠性要求较低，建议设置为0或者100以上
innodb_flush_log_at_trx_commit = 2 默认为1，意思是每次事务提交时都同步日志到磁盘，0代表每秒同步一次，事务提交时不同步，2代表只将事务日志写入缓存，每秒由系统同步磁盘；
